It’s time for a new roof on your home, and you’d like to know how many shingles would be needed for the job. This is something that only professional roofing contractors can do. But maybe you’d like to get to know yourself. Measuring a roof is not always easy. For an accurate calculation, you will need to know a few simple things. Click this Plano Roofing
Roofing contractors have their own lingua franca.
The first thing you should note is that shingles are sold in what roofing contractors refer to as “squares.” A square is a 10×10 foot (100 square foot) space. Normally, one square of simple three tab shingles will require three bundles of shingles. Architectural shingles are heavier and thicker these days. It will take four or five bundles to make a square if you use these.
The first step is to draw what your roof looks like from above by looking straight down at it. Even if you don’t get the exact look, a simple drawing will suffice. The measurements you take will add up to the number of squares needed.
While some are, the majority of roofs do not have two straight sides. Dormers, valleys, and hip parts are common. That’s where things get a bit tricky. Seasoned roofing contractors are accustomed to these situations and should have no trouble delivering the appropriate number of shingles to your house.
How to Calculate the Cost of a Roof Replacement
Let’s start with an easy-to-measure straight roofing portion. Go to the roof’s ridge and take a measurement all the way around. Then, measure the distance between the ridge and the bottom of the roof. Assume the ridge length is 60 feet and the rafter length is 16 feet. 3,600 is the product of multiplying 60×16. That equates to 960 square feet or 9.6 squares.
If you have a hip roof, you will need to calculate the top ridge length, bottom length, and rafter length. Add the ridge and bottom lengths together and divide by two. Then multiply the figure by the length of the rafter. For eg, if the ridge length is 20 and the bottom length is 35, the sum is 55, and 55 divided by 2 equals 27.5. If the length of the rafter is 14, multiply 27.5 times 14. This equates to 385 square feet. Since we need squares, the answer is 3.85 squares.
The hip roof’s apex, or the triangle form, is a simple one. Measure the length from top to bottom, followed by the bottom edge. Divide by two after multiplying the length by the height. Divide the figure by 100 to get the number of squares.
